As I see it, no matter what you use today, it will be eclipsed in a year.

but, a well built machine today will work for 10 years.

If you can get the performance out of todays machines, why wait for
tomorrow ?

Also, it appears that there is no expansion of power, just refinement
of methods, so next years crop of motors and drivers will not be
offering or delivering more power.

The only exception to that is hybred steppers.

Stepper motors will still have power limits and even the new encoder
steppers will slow down to get the work done whereas a bigger servo
would just never skip a beat.

I think the real question is 'what do you need in a drive"?

Then what is missing. Then ask how to get that feature.

The slowing of the stepper to keep in motion and the interaction of
the spindle cutter still needs to be addressed.

USB is a dead end currently unless someone has modified Mach2 to
output to the USB port ?

And, one the USB physical layer is in place, it will need to be
addressed by some year or two of buggy software. Both on the
interface board and MACH2.

The FUTURE is called that because it is not here, it is out there.

USB is around the corner, but no one knows how long the block is till
we reach that corner.

In the mean time, tens of thousands of drives will be put into
service. and thousands of machines will come to life and many
thousands more will make parts.

If you watched the G201a relased and said, I'll wait until it is
bullet proof, then that 5 year wait is almost over. (when was the
G201 introduced ?)

My guess is that SOLID mainstream use of the USB is still 3 years away.

Those who watched know the project was called the G2002 for the year
it was started.
